The 6^th UN Global Road Safety Week, held 17-23 May 2021, highlights the benefits of low-speed urban streets as the heart of any community. The Week calls on policy-makers to act for low-speed streets in cities worldwide, limiting speeds to 30 km/h (20 mph) where people live, work and play. Low-speed streets make for cities that are not only safe, but also healthy, green and liveable. The objectives of the Week are to garner policy commitments at national and local levels to deliver 30 km/h speed limits and zones in urban areas; generate local support for such low-speed measures; and build momentum towards the launch of the Global Plan for the Decade of Action for Road Safety 2021-2030 in late 2021 and the High-Level Meeting of the UN General Assembly in 2022. Partners worldwide are invited to join the #Love30 campaign to build #StreetsforLife.
